I have simple ONC RPC client and server that build on Ubuntu with rpcgen
"(Ubuntu GLIBC 2.31-0ubuntu9.7) 2.31" (under
"5.10.102.1-microsoft-standard-WSL2") but fails to build on Cygwin
("3.3.4(0.341/5/3) 2022-01-31 19:35 x86_64 Cygwin") with rpcgen "(rpcsvc-proto)
1.4".
Naively, it appears that Ubuntu has a much newer version (2.31) than Cygwin
(1.4). Is this the problem?
gzip'ed cygcheck output and the test program and makefile are attached.
Output of "make all"
